Chit – World’s First One-Bit Chemical Hard Drive

Chit – World’s First One-Bit Chemical Hard Drive


In classical computing, records is stored in bits which might be study via physical phenomena consisting of power. You would possibly recognize them as 1s and 0s, additionally called binary code. In quantum computing, it’s stored in quantum bits, or ‘qubits’.

However, computers aren’t the handiest manner we will save information: chemistry is also capable.

Scientists on the Institute of Physical Chemistry of the Polish Academy of Sciences (IPC PAS) in Warsaw have evolved a way in which chemical droplets can save statistics like bits and qubits in a one-bit chemical memory unit called the ‘chit’.


The chit  made of 3 droplets. Between the droplets, chemical reactions take vicinity, circulating cyclically and consistently. This reminiscence is rooted within the Belousov-Zhabotinsky (BZ) reaction, which reacts in an oscillatory manner.

Each reaction creates the reagents important for the subsequent reaction, persevering with without end. These reactions get help by way of a catalyst – ferroin – which reasons a coloration exchange.

There is also a 2d catalyst – ruthenium – which makes the reaction mild touchy.

It’s this mild-touchy characteristic, when blue mild shines upon the response, that forestalls it from oscillating. That’s vital, because it permits researchers to govern the process.


The chit basically lets in for ‘chemical computing’. So, in place of conventional bits, the components are all chemical.

While quantum computing keeps to strengthen, this present day type of computing may want to create a wholly new way to shop, study, and transfer records.

Everything from cellphone generation to labeled digital files rely on our potential to store and read records – the idea of computing.

Completely converting the very base of maximum technology that we depend upon nowadays may want to have awesome outcomes.


Perhaps technologies which are advancing to warfare climate exchange should face major upgrades and adjustments.

Perhaps the devices and motors that we use to explore space will go through modifications as properly.

This type of development may want to absolutely revolutionise so much of the technology that we realize, and in ways we might not even but be able to imagine.
